ANTON MUELLER, OF BRESLAU, GERMANY.

NON-EXPLOSIVE STOPPER FOR BOTTLES CONTAINING LIQUID FUELS.

Specification ofv Letters Patent.

Patented Sept. 30, 1913.

Application filed. May 23, 1912. Serial No. 699,227.

To all whom it may concern:

Be it known that I, ANTON MUELLER, a subject of the German Emperor, and resident of Breslau, Germany, have invented certain new and useful Improvements in Non-Explosive Stoppers for Bottles Containing Liquid Fuels, of which the following is a specification.

This invention relates to an improved nonexplosive stopper for bottles containing liquid fuel, which is represented on. the accompanying drawing.

Figures 1 and 2 are respectively a plan view and side view of same, as attached to a bottle.

a is the stopper which is fitted with a pipe-shaped spout b and by a wire closure 0, in a way known in that art, airtight-1y fixed on the mouth of the bottle, an air pipe 6 passing through said stopper from outside down to the inner bottom of the bottle. The

lower inner end of said air pipe is fitted with a valve (Z which is acted upon by a. spring al while the upper outer end is bent down and directed toward the upper arm of a double-armed operating lever which is fulcrumed on a bracket a of the stopper. The lower arm of said lever is provided with a projection f which engages avertical slot in a shell 9 arranged on the back side of said bracket, the projection being directed toward a ball h inserted in said shell. The upper arm of said lever is connected with a rod 71:, which is adapted to control a stop-cock 2' in the spout b, as well as with a cord Z which leads through the air pipe 6 down to the valve d and which is adapted to control the latter. Owing to the projection f being directed toward the ball h in the shell, it prevents the lever f from being operated and thus the cock 2' and air valve (Z from being opened, as long as the bottle is placed in upright vertical position.

It is therefore necessary to tilt the bottle in order to displace the ball and thus to liberate the projection therefrom, whereupon the spout and air pipes can be openedby a pressure on the lever. Hereby, the gas between stopper and liquid fuel, which is mixed with air, is allowed to escape through the air pipe and thus any danger of explosion obviated. After use, thebottle is again placed in upright position, the lever returning into its inoperative position by action of valve spring (Z pulling the cord Z down, while the ball returns into its operative position by its own weight.

I claim:

A non-explosive stopper for bottles containing liquid fuel, comprising in combination a stopper adapted to be airtightly fixed on the bottle mouth, a spout on said stopper, a stop-cock to close said spout, an air pipe to pass through said stopper and projecting down to the bottom of the bottle, the upper outer end of said air pipe being bent down,

a springpressed valve in the lower end of said air pipe, a downwardly projecting bracket on said stopper, a shell on the back side of said bracket having a front slot, a ball in said shell, a double-armed operating lever fulcruniecl on said bracket and connected with its upper arm to said stop-cock, a projection on the lower arm of said lever designedto engage the slot in said shell and to abut against the ball therein, and a cord between the upper arm of said lever and said valve to pass through said air-pipe, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the witnesses.
